by kwixson, published
Want a better way to level your print bed and get just the right nozzle height? Can you never seem to get the z endstop to stay in one place? Tired of changing start.gcode? Then this thing's for you! With kwixson's adjustable z endstop for prusa mendel, adjusting your nozzle height is as simple as turning a hex key.
This works with my x-end motor mount. Mileage may vary. Fully parametric. Season to taste. STL sized for metric M3 screws and nuts.
Put hex nut in nut well of the clip, fit over x-end motor mount and set with screw. Assemble plunger with spring, screw, three washers and three nuts.
Install and bring nozzle tip into light contact the print bed or plate at the home position. Adjust the end stop plunger to trip the endstop switch. Home the Z axis again to check adjustment. Home the Z axis in each corner of the print bed and adjust print bed height to light contact with the nozzle tip, matching the contact at Home X/Y. Adjust plunger to desired nozzle height (tighten it down by 1/8 or 1/16th turn).
